How can I convert excel to pdf?
I want to put 5 excel files and after I click upload convert them to 1 pdf.
My code: 
    /**
 * Example: DOMPDF 
 *
 * Documentation: 
 * http://code.google.com/p/dompdf/wiki/Usage
 *
 */
public function index() {   
    // Load all views as normal
    $this->load->view('test');
    // Get output html
    $html = $this->output->get_output();
    // Load library
    $this->load->library('dompdf_gen');
    // Convert to PDF
    $this->dompdf->load_html($html);
    $this->dompdf->render();
    $this->dompdf->stream("welcome.pdf");
}
The library:
class Dompdf_gen {
public function __construct() {
    require_once APPPATH.'third_party/dompdf/dompdf_config.inc.php';
    $pdf = new DOMPDF();
    $CI =& get_instance();
    $CI->dompdf = $pdf;
}
}
